NUMBERlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 398,624, dated February .26, 1889.

Application filed November 10, 1887. Serial No. 254,773. (No model.)

To aZZ 10700772 it may concern.-

Be it known that l, \VILLIAM likvtil', of the city, county, and State of New York, have invented certain new and useful lm 'n'ovements in Consecutive-Numbering Machines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which Figure l is a front. elevation of 1n 5* improved eonsecutive-numbering machine; Fig. 2, a rear elevation thereof; Fig. 3, a vertical. section in line .Jr of Fig. 1; Fig. i, a similar section showing the i'iumbering-head forced down in position for imprint; Fig. 5, a detached transverse section of the pivoted pin 5 ber of its parts, to render its action positive and independent of springs, to look its movements so that it shall not be possible for either of the numbering-wheels to overthrow I that the teeth upon said spur-wheels mesh or to turn otherwise than in proper order.

It consists in the construction and combination of mechanism hereinafter described, and particularly set forth in the claims.

In the accompanying drawings, A represents the frame in which the numberinghcad is mounted and permitted to play, said frame being adapted, by means of a bracket and setscrew or other adequate device, to be made fast to a table or other object for support. This frame A constructed in usual form of two side plates, a 0., an upper connectingbar, B, and a central collar, C, which serves as a bearin g for the rod D, carrying the numbering-head. The rod 1) is titted to move freely through the collar (Y, which is suffi ciently extended to afford adequate support and bearing for the rod in its reciprocating L movements therein, and to its lower end is secured a frame consisting of a cross bar or plate, E, from which depend two side plates, F F, to afford bearings for the shafts of the numbering-wheels and the spurqvhecls or pinions of the head.

The numbering-wheels l. 2 4 are mounted upon a fixed shaft, G, supported at either end. in the side plates F F, near the lower end thereof, so as to revolve freely thereon side by side, each indepemlentl ot' the other, and to project below said side plates. Each num berin g-wheel bears upon its periphery, at equal distances apart, suitable typo representing the nine digits and a cipher, and the intervals between the type are cut out to form notches m in v1, adapted to be engaged severally by the teeth n of spur or pinion wheels geared thereto to actuate them. The necessity of secondary pinions or spur-wheels is therebv obviated.

The ends of the shaft G are made to project through the side plates F F far enough to pass into longitudinal grooves j j in the side plates a. a of the supporting-frail]e, (see dotted lines Fig. 1,) to guide the head in its reciprocating movements.

A separate spur-wheel or pinion, ll, is provided for each numbering-wheel, and these spur-wheels are all mounted side by side upon a shaft, 1, secured at either end in the side plates F F, parallel with and at a suitable distance above and in front of the shaft G, so

into the notches of the numbering-wheels. Each pinion H is fitted with ten teeth, n n, to correspond with the number of notches m m in the numberirig-wheel, to which it is geared, so that the latter will make a complete revolution at each complete revolution of the former. One tooth, 1', (see Fig. 1,) upon each spur-wheel is made so wide that when it engages the numbering-wheel to which the spurwhcel is geared it will also overlap and engage the numbering-wheel next on the left, so that both wheels will be turned by the same tooth and the second whee]. moved one step at each revolution of the first.

The units-wheel 1. is moved one step at each upward movement of the numbering-head by means of a finger, K, projectinfrom a sleeve,

K, mounted to rotate upon a stud, L, pro jecting horizontally from the side plate a of the supporting-frame A, parallel with the shafts Sr and I, and in front of and below thelatter,

so that the finger K, when held in a horizontal position, shall engage the teeth of the spurwheel geared to the units-wheel. The finger is brought automatically to its normal horizontal position by means of a spiral spring,

10 R, interposed in a suitable recess between the sleeve K and stud li,npon which it turns,

and is stopped in said position by means of a tooth, O, projecting from. the end of a collar,

0', fixed upon the stud L, into a recess, Q, cut

in the adjacent on d of the sleeve K. (See Fig.1.)

The recess Q isso disposed that when the numbering-head is lowered so as to bring a tooth, or, of the spur-wheel ll into contact with the finger K the latter will be free to give by the turning of the sleeve K, although so soon as the tooth n has passed down out of engagement with said finger K the latter will, under the influence of the spring R, turn 2 5 back to its first position in readiness to engage the same tooth a when the numberinghead is elevated. As the head is lifted, the finger o2, striking the tooth K, which is held fast in this direction, will be made thereby to turn the spur-wheel H, and with it the unitswheel, one step, so that the units-wheel will thus be actuated one step after each impression made thereby by reason of its being carried down upon the paper beneath it.

3 5 A reverse movement of the several numboring-wheels is prevented in the customary manner by means of pawls S S, pivoted upon a cross-bar, S, to drop into engagement with the teeth of the spur-wheels H H, geared to the numbering-wheels, this engagement being enforced by springs S All the numbering-wheels other than the units-wheel are at all times positively locked, so as to be fixed in their positions excepting at the moment when the projecting tooth of the units-wheel is brought into position to actuate the tens-wheel, being released only during the interval in which the movement of the tens-wheel occurs. This positive lock of the wheels is accomplished by means of a dog, consisting of a plate, 12, (see Figs. 2, 3, and' h) made wide enough to overlap all the numbering-wheels excepting the units-whee], and which is pivoted at one edge upon a transverse rod, 13, extending across the head parallel with the axis of the wheel. The free edge of the plate or dog is suitably bent and shaped to engage the notches m m in said wheels, and it drops into said notches automatically by its weight, so as to engage them all simultaneously.

fThe edge of theplate 12 is prevented from rising out of said notches, and is thereby made I to hold and lock them positively by'm'eans of an arm, l-l,projecti1'1g from one end of the pivotal edge of the plate radially in the opposite direction in position to bear upon the periphery of a circular disk, 15, made fast to the outer face of the spur-wheel I l, actuating the units-wheel. So long as the end of the arm 14L bears upon the concentric periphery of said disk the dog 12 is held fast in its engagement with the numbering-wheels tolock them.

The release of the dog at the moment the unitsavheel is in position to actuate the tens wheel is iern'iitted by means of a circular notch, 16, cut in the periphery of the disk 15 in such position as to allow the arm 11 to move inward therein at the desired moment. The dog is then left free to slip out of the notches and to remain free long enough to permit the numberin g-wheels, or any one or m ore of them, to turn forward one step in unison with the one step of the units-wheel. The next sueceeding step of the unitswheels, by carrying the notch 16 away from the end of the arm 1+, will again lift it, and thereby operate, in manner as described, to lock the dog.

The numbering-wheels are inked after each impression by means of an inking-pad, T, fitted upon a swinging bracket, U, pivoted to a cross-bar, U, in the frame A, so as to be free to swing under the wheels and into contact with the type thereon, when they are elevated to'their highest position.

The movement of the swi ngi ngbravket and its pad is produced and controlled by a double link, V, pivoted at one end to a cross-bar, V, upon the bracket and at the other to a parallel cross-bar, V secured to the sideplates, F F, of 'the numbering-head. The link is so adjusted in length and the pivotal bars V and V upon which itswings, so located that when the numbering-head is elevated the link is brought nearly to a vertical plane, drawing the bracket inward, so as to carry its pad T under and into contact with the lowermost type on the numbering-wheels, as shown in Figs. 1, 2, and hen, however, the numberinghead is depressed, the link is thrown out to and beyond a horizontal plane, as shown in Fig. 4, thereby causing the bracket to swing out from the head and withdraw the pad wholly clear of the numberingavheels.

The connection of the numberingsmachinc with an adding or check or printing machine is effected by means of a pivoted lever, 20,

oscillated by the movements of the adding or.

printing machine, and whose free end is passed through a slot, 21, in the upper endof the rod D. here the movementsof the lever 20 are positive and invariable, I insert in the head of the rod D a setscrew, 22, whereby the stroke of the rod D, actuatedby the lever 20, maybe adjusted, so that as the inking-pad wears away its contact with the numbering-wheels aftereach impression therefrom may befmaintained by shortening. the stroke .ofthe'rod D, this result being obtained by screwing inward the set-screw 22, so as to reduce the length of the slot 21. p

The inking-pad consists of an absorbent layer of one or more thicknesses of suitable material adapted to retain a proper supply of ink, and which is secured in any suitable manner upon a metallic plate, U 2

In the operation of the machine, when the nu mberin g-head is forced downward by pressure upon the rod 1), the inking-pad will, as the head descends, swing out from under the nu mberin g-wh eels, leaving them clear to m ake their impression upon the surface to which they are applied. men t takes place the horizontal tooth on the first spur-wheel H will strike the actuating finger K, carried by the sleeve K on the fixed stud L; but said sleeve K, being free to re volve upon the stud in the direction of the lI'IOVOlTKlll will simply turn the finger K out of the way, so that the smut-wheel may freely As this downward movepass, and will then turn back automatically j to its first position under the influence oi. its

spring. Upon the return upward movement of the head, however, when said horizontal projecting tooth of the spur-wheel ll strikes the finger K, the finger, being prevented from turning upward, will operate to move the spurwheel one step, which said movement will be communicated to the units-wheel geared thereto. Thus at each upward movement of the head after each impression produced therewith the units-wheel will be automatically turned far enough to change the number.

At each complete revolution of the unitswheel it will move the tens-wheel one step by means of the customary device for this purpose, horeinbefore described, and at the moment this movement of the tens-wheel is effected the locking-dog 12 is freed from the Q nu mbering-wheels to permit them to turn by the passage of the end of the arm it into the 1 ed in said reciprocating frame, ofthe link V,

notch 10 in the periphery of the locking-disk 15, as above described.

It is evident that spurwvheels or pinions meshing directly with peripherally-cogged type-wheels may be employed in adding-machines as well as numberingheads to avoid extra gears, and I contemplate the use thereof l herein set forth.

in all such machines.

I claim as my inventionl. The comliination, in a numlwring-machine, of an outer stationary frame, an inner moval'ile frame reciprocating therein, parallel shafts mounted in said inner movable frame, 1 a series of one or more peripherally-cogged nunlberiiigwlieels revolving upon one of said shafts and each bearing type upon their cogs,

corresponding spur-wheels revolving upon the other shaft and gearing severally with said cogged numbering-wheels, a yielding finger projoctin g from the stationary frame in position to be engaged by a tooth of the first spurwheel at each reciprocating movement of the inner frame, a stop preventing said finger from yielding under the pressure of the tooth as the frame moves inward, and a spring actuating said finger to carry it to its normal position, all substantially in the manner and for the purpose herein set forth.

2. The combination, in a numbering-ma chine, of an outer stationary f 'ame, an inner movable tram e reciprocating therein, parallel shafts mounted in said inner movable frame,

a series of cog-wheels having type upon the cogs and revolving upon one of said shafts, a corresponding series of spur-wheels revolving upon the other shaft and gearing severally with said type-wheels, a single tooth projecting laterally from each spur-wheel to engage the next adjacent type-wheel at each complete revolution, a disk upon the outer side of the first of said spur-wheels, said dis]; having a single notch in its periphery, a wide dog pivoted to the movable frame upon an axis parallel with the axial shafts of the spur and type wheels, and which engages simultaneously all the type-wheels excepting the first, and an arm projecting from the dog into contact with the periphery of the disk, all substantially in the manner and for the purpose herein set forth.

The combination, with the swinging inkpa-d bracket U, pivoted to the fixed frame A, the reciprocating frame traversing in said fi .ved f ra me, an d the n umberi ngwheels moun tpivoted to the swingingbracket-frame and to the frame carrying the numbering-wheels, whereby the movements of the head operate to swing the bracket and its pad in and out of contact with the numbering-wheels, all substantially in the manner and for the purpose In testimony whereof I have signed my name to this speci tication in the presence of two subscribing witnesses.
